NOTE: This DTC will not clear until the vehicle has been driven above 48 km/h (30 mph) with input from the steering wheel rotation sensor.
NOTE: Repair all other non- communication DTCs before repairing DTC C1963.
GO to PINPOINT TEST F .
C1991 Module Calibration Failure Using the scan tool, CARRY OUT the IVD Initialization sequence. FOLLOW the scan tool directions. CLEAR the DTCs. REPEAT the self-test. If DTC C1991 is retrieved again, INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE .
C1996 Active Yaw and/or Roll Control Disabled GO to PINPOINT TEST I .
C2769 Longitudinal Acceleration Sensor Electrical Failure This DTC is related to a 4WD ABS module concern. If this DTC is set on this vehicle an incorrect ABS module has been installed, the ABS module has not been configured or the ABS module has not been configured correctly. VERIFY the module part number matches the required module for the vehicle. If the part number does not match the required part number for the vehicle. INSTALL the correct ABS module. CARRY OUT the Programmable Module Installation (PMI) manually from the as-built data. REFER to MODULE CONFIGURATION SYSTEM article. TEST the system for normal operation.
C2770 Longitudinal Acceleration Sensor Plausibility Failure This DTC is related to a 4WD ABS module concern. If this DTC is set on this vehicle an incorrect ABS module has been installed, the ABS module has not been configured or the ABS module has not been configured correctly. VERIFY the module part number matches the required module for the vehicle. If the part number does not match the required part number for the vehicle. INSTALL the correct ABS module. CARRY OUT the Programmable Module Installation (PMI) manually from the as-built data. REFER to MODULE CONFIGURATION SYSTEM article. TEST the system for normal operation.
C2777 Sensor Cluster Bus Failure GO to PINPOINT TEST G .
C2778 Sensor Cluster Power Supply Failure GO to PINPOINT TEST G .
U0001 HS-CAN Communication Bus REFER to MODULE COMMUNICATIONS NETWORK article to diagnose the HS-CAN bus.
